I heard that you can pay through UnionPay, but I haven't tried it myself since I have a foreign bank card. If anyone needs a $3 discount, here's the code: ***. The app is excellent; the internet is cheaper than the best roaming rates from mobile operators! I used eSIM in Egypt, Turkey, and Thailand. On the iPhone, it connects immediately upon arrival in the country. However, it's important to set up the phone correctly and catch the network; otherwise, nothing will work.
